What causes the sweet pepper to be empty?
In the rural areas, most of the previously grown sweet peppers were cultivated in open fields. Later, it was found that greenhouses were planted with sweet peppers, which had the advantages of high yield and long fruit harvesting period. Some of the growers used greenhouse cultivation. However, due to the poor management of the greenhouse, the temperature and humidity in the shed cannot be controlled, and the sweet pepper is often formed "empty", resulting in a reduction in production. So what is the reason for the sweet peppers? How do we prevent the sweet peppers from being empty? Please see below for details! First, the main reason for the "empty" of sweet pepper 1. The slow seedling period is too long. The slow seedling period of sweet pepper is generally six or seven days. During the slow seedling period, it is required to close the greenhouse. Do not ventilate. The temperature of the shed should be maintained between 30 and 35 degrees. At night, the curtain should be covered with straw to keep warm and antifreeze to accelerate. Slow seedlings. However, if the slow seedling period is too long, the high temperature and high humidity duration in the greenhouse will prolong, which may easily cause the plant to grow. 2. Ventilation is not timely. Ventilation should be promptly ventilated, so that the shed temperature is reduced to 28 ° C ~ 30 ° C, then every shed temperature above 30 ° C should be ventilated and cooled. Otherwise, the temperature in the shed is high, the soil moisture evaporates faster, and the humidity in the shed exceeds 60%. The first door is difficult to sit on. Once the first fruit can't sit, the nutrients will be used in the growth of branches and leaves. Intensify the length of the plant, causing a vicious circle and the phenomenon of open peppers. Second, to prevent the formation of sweet peppers, we can take the following preventive measures After slow seedlings, ventilation is required to reduce the temperature and humidity in the shed. Keep the temperature in the shed between 28 and 30 degrees, then slowly lower the temperature until the flowering and fruiting period, keep 20 ° C ~ 25 ° C. When the minimum outside temperature is not lower than 15°, ventilation should be carried out during the day and night, so that the sweet pepper plants can grow short, have short internodes, and have many fruit sets. To strengthen water and fertilizer. The leaves of sweet pepper are small, and the water evaporation is not large. After the seedlings are harvested, it is generally not easy to water before harvesting. Otherwise, it is easy to cause falling flowers and fruits. When the first layer of fruit begins to harvest, it is necessary to strengthen watering, fertilization, multi-application of organic fertilizer, and increase of phosphorus and potassium fertilizer, which is conducive to the high yield of sweet pepper and the quality of sweet pepper.
